FIRE-HOSE NOZZLE.

T0 ctZZ whom, it may concern..-

Be it known that I, ARTHUR WYLIE HAINES, a citizen of the United States,residing at Lorain, in the county of Lorain and State of Ohio, haveinvented new and useful Improvements in Fire-Hose Nozzles, of which thefollowing is a specification.

My invention relates to nozzles for fire-hose; and the objects of thesame are to provide means for changing the character of the stream, asemergencies arise requiring such change, from a round stream or volumeof water to a spray or fiat sheet to protect the hoseman; and anotherobject is to provide, also, means for quickly making such changes in thestream or to completely cut 06 the supply; and still another object isto produce a simple and inexpensive device which shall be efficient,easily operated, and not liable to get out of order. I attain theseobjects by means of the construction shown in the accompauying drawings,in which-- Figure 1 is a longitudinal section through the nozzle andshowing the valves in operative position. Fig. 2 is a similar viewshowing the valves thrown out of position for use. Fig. 3 is an end viewof the nozzle with the valves closed.

Like numerals designate like parts wherever they occur in the diiferentviews.

The numeral 1 designates a hosenozzle having upon its outer surface nearits end a spiral groove 2 of comparatively-quick pitch to form ascrew-threaded bearing for an adjustable sleeve 3. The sleeve 3 isinteriorly threaded at 4 to lit the groove 2 and is provided with milledknurls 5 on its outer surface to aid in turning it. The outer portion ofthe sleeve is enlarged to form a bell-shaped or flaring exit end 6. At aslight distance from the outer edge of the flaring end of the sleeve twooppositely-disposed pivot-bearings 7 are secured by suitable means, asby headed rivets S. Pivoted between the arms of each of these bearingsis a valve-stem 9, each of said stems having formed thereon asemispherical valve 10, which are designed to close together to form aball-valve for completely closing the end of the nozzle or which may beadjusted in close proximity to the nozzle to deflect the stream in theform of a spray or sheet. The tail end 11 of the valvestem 10 is ofsector shape and passes through an aperture 12 in the side of the bell.

A concave washer or plate 13 is connected to the end of the nozzle 1 byscrew-threads, and the periphery of this washer fits the in terior boreof the bell end of the sleeve. Fitted upon the outer surface of the bellis a sliding ring 14, which is forced toward the open end of the bell bya spring 15, held between a stop-ring 16 and a flange 17, bearingagainst the terminal ends of valve-stem sectors 11. The stop-ring 16 isattached to the hell by screws 18.

The end of the nozzle 1 is ground to form a water-tight seat for thevalve 10.

The invention is operated as follows: When it is desired to throw around stream or volume, the sleeve 3 is screwed outward toward the exitend until the innerwall of the bell is seated upon the contiguoussurface of the washer 13. The spring 15 presses down upon the flange 17of the ring 14, and said flange bears upon the sectors 11 and throws thevalves outward to the position shown in Fig. 2. When the ring 14 isforced by hand in the opposite direction and the sleeve moved upward onthe nozzle, the valve-sections assume the position shown in Fig. 1 or aposi tion to serve either to cast a spray or sheet of water or to closethe opening in the nozzle, dependent upon the degree of adjustment ofthe sleeve.

' Without desiring to be limited to the exact construction shown, as Iam aware that certain changes may be made in details without departingfrom the spirit and scope of the invention, what I claim is 1.Ahose-nozzle, consisting of an exteriorly= threaded nozzle, aninteriorly-threaded sleeve fitting said nozzle,semispherical valvesadapted to lit a valve-seat at the end of the nozzle, valve-stemspivoted to the sleeve, and means whereby the valve-sections may bethrown into or out of action, substantially as described.

2. A hose-nozzle consisting of a sleeve fitted to move on the nozzle andcarrying a pair of semispherical valves, stems secured to thevalve-sections and pivoted in an enlargement of the sleeve, sectorsformed on the ends of the valve-stems and passing through apertures inthe'sleeve, and a spring-propelled ring for acting upon the sectors tooperate the valves, substantially as described,

sleeve carrying a pivoted valve having sector ends passing through thesleeve, and a ring for acting upon the sectors to open and closethevalve, substantially as described. U 4. A hose-nozzle, a threadedsleeve surrounding it and having an enlarged outer end,

. re a sectional valve pivoted within the enlarged end, sector endspassing throughth e sleeve,

v a V and means for adj usting the valve to and from 3. Afhose-nozzleprovided with a threaded.v

its seat, for the purpose described.

In testimony whereof I have hereunto set my hand in presence oftwosubscribing wit- I 5 nesses.
